Paper Abstract

Investigations of optical recording processes in amorphous chalcogenide layers were extended to the compositionally modulated amorphous nanomultilayers made of different pairs of chalcogenide glasses from As-S(Se) systems or pairs of chalcogenide glasses and metals, dielectrics. This type of recording is connected to the light-stimulated mass transport across the interfaces, possible phase transformations and correlated changes of optical parameters (absorption, refraction, reflection). The interconnections between the compositional modulation at nano-scale dimensions (~3-10 nm) and possible improvement of recording parameters (the rate and degree of optical bleaching, darkening, local changes of the thickness and of the refractive index, spatial resolution) were established.
